Crystal structure analysis of novel complex hydrides formed by the combination of LiBH4 and LiNH2
Source abstract
Abstract
Combination of LiBH4 and LiNH2 by ball milling forms the series of novel complex hydrides Li2BNH6, Li3BN2H8 and Li4BN3H10, depending on the combination ratios. The crystal structure of Li4BN3H10 analyzed by synchrotron X-raydiffraction measurements is determined to be a cubic system (space group: I213) with the lattice constant of a=10.673(2)A. It should be emphasized that Li4BN3H10 is an ionic crystal which is composed of a lithium cation Li+ and two different kinds of the complex anion [BH4]- and [NH2]-. These anions are located in the vertex and face-center of the cubic sub-lattice, and the lithium cation Li+ in the interstitial site between the anions, respectively. The other series of complex hydrides, Li2BNH6 and Li3BN2H8, are also predicted to possess similar structures composed of a lithium cation Li+ and two different kinds of the complex anion [BH4]- and [NH2]-.
